Title: Improvements in and relating to the production, storage and conveyance of foam
IPC: A62D1/02
Filed: 1938-11-23
Abstract: 531,679. Making foam. LOWENSTEIN, L. Nov. 23, 1938, Nos. 34111 and 34112. Convention dates, Nov. 23, 1937, and March 31, 1938. [Class 47 (ii)] A process for the production, storage, carriage and dehydration of foam, in which particles in solid or gel form are entrained, is characterized by the use of containers having flexible, waterpermeable walls. The foam may be produced by placing dry foam-forming reagents in the flexible water permeable container, and admitting water to the container so that foam is formed in, and fills it. The reagents may be placed in a closed bag, and the bag then immersed in water, the chemicals reacting with the necessary quantity of water, any excess of the latter then draining away. The bag, filled with foam, may be thrown upon a fire, or may serve as a life-belt or buoy. Alternatively, the foam may be forced by pressure through a closable opening in the bag. For foam baths or compresses, a bath may be lined with a sheet of flexible permeable material, within which the foam is produced. The margins of the sheet are then folded over the foam, to assisting in maintaining its temperature. For such purposes, medicinal mud may be embodied in the foam. Specification 486,113 is referred to.

Title: Cyanoformamide
Filed: 1962-09-10
Abstract: Cyanoformamide is made by reacting cyanogen with a monohydric alcohol to form the corresponding cyanoformimino ether which is then reacted with anhydrous hydrogen halide, particularly hydrogen chloride, to form cyanoformamide and the halide corresponding to the alcohol.  It is preferred to use boric acid of a Lewis acid, especially aluminium, tin, iron or zinc chloride or boron trifluoride as a catalyst for the ether splitting reaction, which may be conducted in an inert solvent, e.g. an ether, or a chlorinated aliphatic or aromatic hydrocarbon. Allyl alcohol is the particularly preferred member of primary alcohols, which includes alkyl, alkenyl, cycloalkyl, cycloalkenyl, aralkyl or aryl substituted ones, since the allyl halide may be readily hydrolyzed for cyclic re-use in the reaction.  In the examples the preparation of cyanoformamide via the methyl, and alkyl ethers are described and the effectiveness of the various ether splitting catalysts is compared.

Title: Improvements in and relating to the control of dynamo-electric machines
Filed: 1922-12-23
Abstract: 204,611. British Thomson-Houston Co., Ltd., (General Electric Co.). Dec. 23, 1922. Switching systems; regulation, automatic systems and apparatus for.-In an automatic substation system, the operation of connecting a generator to bus-bars is preceded by reduction of the generator voltage to the minimum, and further, if necessary, by restoration of generator voltage to approximate equality with that of the bus-bars. After connection, the machine is automatically regulated for constant voltage, subject to a limit of maximum output. The generator 48 is provided with a field rheostat switch 41 operated by a reversible motor 38. Main switches 4, 18, the latter having overload release features, are adapted to connect the generator to bus-bars 1. The sequence of operations is started by the closure of a switch in a control circuit 50, and thereafter proceeds automatically. With the mains disconnected as shown, the effect of closing the control circuit is to drive the motor 38 in the direction to insert resistance in the generator field, and then, when full resistance is in, to energize magnets 3, 19 whereby the main switches are closed. If, however, the bus-bar voltage exceeds that of the generator, the switch 2 remains open temporarily, and a difierential voltage relay 9 is moved so as to reverse the motor 38 until the generator voltage is raised above that of the bus-bars, after which the closure of the switch 2 takes place. Once connection has been established the motor and rheostat act as an automatic regulator under the control of a voltage relay 28 with the additional provision of a series relay 34 to limit the maximum output of the generator.
